The study evaluated the response of pea (Pisum sativum cv. Avola) to arbuscular mycorrhizal fungi (AM) species Glomus mosseae and Glomus intraradices and Rhizobium leguminosarum bv. viceae, strain D 293, regarding the growth, photosynthesis, nodulation and nitrogen fixation activity. Pea plants were grown in a glasshouse until the flowering stage (35 days), in 4 kg plastic pots using leached cinnamonic forest soil (Chromic Luvisols - FAO) at P levels 13.2 (P1) and 39.8 (P2) mg P/kg soil. The obtained results demonstrated that the dual inoculation of pea plants significantly increased the plant biomass, photosynthetic...
New Rhizobium leguminosarum bv. trifolii isolates: Evaluation of competitiveness for clover nodule occupancy

An interrelationship between introduced and indigenous rhizobia focused on their competitiveness in nodulation was evaluated in a soil pot experiment. Clover seeds were inoculated by six different gradual concentrations of inoculum of two effective Rhizobium leguminosarum bv. trifolii isolates (inoculation strains 1/2 and 14/2). At the beginning of flowering, clover plants were removed from the pots, and nodules from each pot representing different degrees of inoculum level were taken for reisolate cultivation. The PCR technique was used for the identification of rhizobial reisolates, random amplified polymorphic DNA product patterns...

The effect of three different growing methods, and plant age on the yield of purple coneflower (Echinacea purpurea L.) Moench., Asteraceae are described. The weight of fresh and dry mass of rhizomes increased significantly with the age of the plants. Independently of the age, the highest yield of rhizomes (1779 g/m2 FW - 589 g/m2 DW in the third year) was found in the plants grown from root cuttings and the smallest (385 g/m2 FW - 108 g/m2 DW in the third year) from seeds sown directly into the soil. A similar dependence was obtained in the yield of flower heads. No relation was noticed between the...

The effect of coniferyl alcohol as a precursor of flavonolignan biosynthesis on silymarin components production in Silybum marianum suspension culture was studied. Coniferyl alcohol showed the changes in silymarin complex production. Silydianin was detected mainly in the control samples of cultivated cells. A significant increase of silydianin was observed only after 72 h of the application of 46µM coniferyl alcohol. No other components of the silymarin complex (silychristin and silybin) were detected; neither in control samples nor after the precursor feeding. But the increased accumulation of taxifolin (flavanole) was very interesting....
Ecobiological study of medicinal plants in some regions of Serbia

Ecobiological study of medicinal plants includes the analysis of particular soil features and the ecological indexes of plant species as site indicators. Two experimental serpentine areas in northwest and central Serbia were selected to identify the potential limiting factors for medicinal plant harvesting. Soil analysis is done according to ICP methodology - ICP Forest Manual, Part III, Soil Sampling and Analysis (1998). Floristic and phytocoenological investigations were carried out by Wasthoff-van der Maarel (1973). The assessment of soil quality is based on the calculation of indicator values of available nitrogen (N), heavy metals, and the sensitivity...
Estimation of red clover (Trifolium pratense L.) forage quality parameters dependingon the variety, cut and growing year

A field trial was conducted to determine the nutritive value of eight Slovak and Czech red clover varieties and to quantify the effects of variety, cut and year on red clover forage quality. The differences between forage quality of the evaluated red clover varieties were significant for protein supplied when energy is limited in the rumen (PDIE), intestinal digestibility of rumen non-degraded protein (dsi), net energy values and ash content (P < 0.01). The achieved results show that the surpassing forage quality was given by diploid Viglana variety with high protein and energy values. The forage of tetraploid varieties Javorina and Dolina...

Salt-tolerant Gevas Sirik 57 (GS57) genotypes and salt-sensitive 4F-89 French variety, previously determined in our preliminary study, were used in the study. The genotype and the variety exposed to 100mM NaCl application developed different mechanisms to be protected against toxic effects of Na+ ion. Salt-sensitive 4F-89 French variety let Na+ accumulate in all organs. On the contrary, salt-tolerant GS57 did not avoid salt and acted selectively among ions; the majority of toxic ion Na+ accumulated in old leaves and shoots and the plants did not transport them into young leaves. K+ accumulation was high in...
